Description

Inline specialty water treatment

Restore gentle mineral character and near-neutral alkalinity to RO water with four natural mineral media

This 3/8″ quick-connect remineralization filter is designed as the final stage after reverse osmosis. Its four-media blend—FIR ceramic, coral red stone, maifan stone, and bioceramic media—slowly contributes trace minerals and gently raises pH, helping purified water taste smoother and more naturally balanced.

Water profile & wellness context

Four-Natural-Media Remineralization Blend — Inside the filter are four carefully selected mineral media: FIR ceramic, coral red stone, maifan stone, and bioceramic balls. As purified water passes through the cartridge, the media gradually contributes calcium, magnesium, potassium, and other trace minerals, helping restore some of the natural mineral character removed during reverse osmosis.

The result is water with a smoother, fuller, more natural taste and a gently balanced, near-neutral pH rather than strongly alkaline water. This makes it a good choice for customers who enjoy the purity of RO water but prefer a more mineral-balanced taste and mouthfeel.

Points:

  • 4 Natural Mineral Media — FIR ceramic, coral red stone, maifan stone, and bioceramic media.
  • Restores Mineral Character — Helps add selected trace minerals back to low-TDS RO water.
  • Smoother, More Natural Taste — Mineral conditioning helps reduce the flat taste sometimes associated with highly purified water.
  • Gentle pH Balance — Designed for mild remineralization without making the water strongly alkaline.
  • Ideal Final RO Stage — Adds mineral conditioning after the membrane has completed the primary purification process.

Compatibility

Match the filter to the water-quality goal

Designed for compatible RO and inline systems using 3/8″ OD tubing. Systems using 1/4″ tubing require an appropriate reducer/adapter or a 1/4″ version.

Gentle remineralizer and taste/pH conditioner, not a high-alkaline or medical-wellness filter.
